Combined tibiofibular embracing fixator

Abstract

The invention relates to a combined tibiofibular embracing fixator which comprises a fibula embracing body, fibula embracing arms and tibia embracing drawing hooks, wherein the fibula embracing arms and the tibia embracing drawing hooks are integrated into a whole; the fibula embracing body is provided with the fibula embracing arms and the tibia embracing drawing hooks; the tibia embracing drawing hooks are positioned among the fibula embracing arms; and both sides of each group of fibula embracing arms and both sides of each tibia embracing drawing hook are provided with antiskid ratchets. The combined tibiofibular embracing fixator has the advantages of simple technological shape and reasonable structure, and is favorable for reducing the operation of manually damaging bones in an operation; and the combined tibiofibular embracing fixator is convenient in utilization in the operation and is firmly and reliably fixed. After the combined tibiofibular embracing fixator is installed, not only fibula fracture can be treated, but also distal tibiofibular separation puzzled by clinical doctors can be treated. The combined tibiofibular embracing fixator of the invention has excellent application value and application prospect; a satisfactory curative effect can be obtained by reasonable application; and compared with operations for treating ankle fracture combined with distal tibiofibular joint separation and the like by using absorbable screws, the combined tibiofibular embracing fixator is more favorable for improving the living quality of patients to a certain degree and has excellent economic and social benefits.

Description

technical field [0001] The invention relates to a medical device, in particular to a tibia-fibula joint embracing device for internal plant medical materials which is beneficial to the benign healing of fractures and is used in surgery and orthopedics for implantation in bone bodies. Background technique [0002] Ankle joint injuries are often accompanied by tibiofibular separation. Conventional treatment methods: use lag screws or thick cancellous bone screws for reduction and fixation. This kind of treatment often has complications, such as: the fixation of the three-layer cortex is not firm, the screw breaks after the fixation of the four-layer cortex, etc., and the screw insertion point is poor or cannot be grasped due to the type of fracture. When using hook plate to treat tibiofibular joint separation, tibiofibular semicircular groove external support, or absorbable screw to treat ankle fracture and inferior tibiofibular joint separation, the screws often need to be re...

AI Technical Summary

Problems solved by technology

[0003] The present invention is to solve the problems in the prior art that the screws are not firmly reset and fixed, and the screws often need to be taken out after surgery, which increases the pain of operation and economic burden and the screws are easy to break, etc. The problem is to provide an elastic modulus that is only a quarter of that of other stainless steel implants, which is similar to the elastic modulus of human bones, and the stress shielding after implantation is small, which is conducive to the benign healing of fractures.
